Fig. 20 is a fragmentary view in elevation of As illustrated, the rifleembodying the present invention is of the shoulder type and is adaptedfor selective automatic or semi-automatic firing, being provided with aself-loading mechanism. The rifle comprises a barrel 25 (Figs. 1, 2, and6) 4threadeclly secured toa receiver 26 and a stock 21 fixed to the rearend of said receiver. A box cartridge magazine 28 is operativelyattached to the receiver, being held by means of a pushibutton device 29of well-known construction. A

forward hand grip or forearm 30, which serves thereto by a bracket 35.Passage 34 preferably extends through the end wall of the cylinderproviding an expansion chamber in the Cylinder even when the piston isat the end of its travel. A

YhollowY piston rod 36 secured at one end to said piston is slidablymounted at the other end on a hollow guide rod 31, the latter beingsupported at its free end by a bracket 38 fixed to receiver 26. Acompressed coil spring 39 is contained within rods 36 and 31 and acts tomove piston 33 in the direction of the cylinder head. Forearm 36` coversand guards the moving parts connected to cylinder mechanism 32, 33 andis supported at one end by bracket 38, the latter h-aving a pai-r ofgrooves 38a (Fig. 4) formed therein for receiving a plate member a.fixed to said forearm. The other end of said forearm is secured to thebarrel 25.

To transmit the motion of piston 33 to the mechanism in receiver 26, anvarm or connecting rod 46 connected at one end to piston rod 36 extendsrearwardly to said receiver and is slidably mounted for reciprocation ina groove 4| (Figs- 3 and 4) formed in av laterally projecting portion 42of said receiver. Groove 4| extends longitudinally for substantially theentire length of the receiver and opens outwardly so that arm 46 may bereadily positioned therein during assembly. A. longitudinal slot- 43 inthe wall of the receiver connects groove 4| to the interior of thereceiver and a pair of longitudinally spaced lugs 44 and 45 carried byarm 4|) adjacent the end thereof extend through said slot into saidreceiver, said lugs being adapted to engage and actuate the reloadingand ring mechanisms in the receiver in a manne-r more fully describedhereafter.v

To cover groove 4| so as to prevent foreign material from entering thereceiver through slot 43. and to provide. manual means for actuating therifle mechanisms, a member 46 is slidably mounted in a pair of grooves41V disposed in the side walls of groove 4| and has a handle 48 formedtherewith. Slide 46 (Fig. 3) is connected to arm 46 by means of aretractable pin 49 mounted in-a recess 50 in handle 48. A coil spring 52in said recess urges said pin into engagement with the rear end of aslot 53A in arm 40, the tip 48a of said pin bein-g formed with a pair ofparallel sides spaced apart a distance equal to the width of said slot.A lug 54 mounted on the pin extends through a recess 55 in handle 48 andsaid lug and recess act as a bayonet joint whereby pin .49 may be helddisengaged from slot 53. The latter extends forwardly from said pin sothat movement of arm 4B to the rear will not be transmitted to slide 4'6while rearward movement of the latter will retract said arm. A pin 5|(Fig. 3) resiliently mounted in a recess in the side wall of receiverportion 42 engages a recess in slide 46 and fixes the latter againstinadvertent movement due to recoil and handling but does 4 not offer asufficient resistance to materially affeet the manual operation of saidslide.

A novel bolt mechanism 56 comprising a cartridge-engaging cylindricalportion 51 (Fig. 6) and a rear block portion 58 is slidably mounted forreciprocation in receiver 26. Portion 51 ex-V tends into the lcartridgechamber 59 of said receiver and is provided with a cantilever extractorspring 60 and an axially extendingy flange 6| for engaging a cartridgerim in the well-known manner during the forward motion of said portioninto said chamber. Cartridges are fed into chamber 59 by magazine 28,the latter having a spring actuated follower 62 (Fig. l) for moving thecartridges into said chamber. The spent cartridge shell is ejectedthrough opening 63 (Fig. 1) in the receiver during the rearward mo tionof bolt mechanism 56, being engaged by a lug 63a (Figs. 6 and 21)extending into said receiver on the side thereof opposite said openingand being pivoted thereby about extractor spring 60. in cylindricalportion 51.

Novel means for locking bolt mechanism 55 against movement yduring ringare provided and, as shown, comprise a. member 64 (Figs. 6 and '1)pivotally mounted on block 58 adjacent the front end of the latter andextending rearwardly in receiver 26. When member 64 is held in elevatedposition, as shown in full lines in Fig. 6, said member engages the endsof a pair of laterally spaced shoulders or abutments 65 formed in saidreceiver and provides a positive lock for bolt 56. Member 64v comprisesa pair of arms 64a which are integrally joined at the rear or receiverengaging end of said member and said arms are pivotally mounted on bothsides of a vertically extending central portion 66 of block 56 by meansof a pin 61. To retract bolt 56, member 64 mut be lowered and toaccomplish this a control link 68 is mounted for pivotal movement on oneof arms 64a, a depending bracket 69 being preferably formed on said armwith an opening 16 therein for receiving a pin 1| carried by said link.A recess 12 in block 58 receives bracket 59- and an adjoiningrecess 13receives link 68, the bottom wall V14 of the latter recess serving tosupport said link when the latter holds member 64 in elevated positionand to guide said link during the pivotal movement thereof to controlsaid' member. An opening 15 (Fig."1) in the lower half of control link68 is adapted to be engaged by lug 44 on arm 46 (Fig. 3). VMovement ofarm 4U rearward pivots said link and depresses member 64, rendering bolt56 Lug 45 (Fig. 3)

a longitudinally extending pin 18 having a iiringv tip 19 and adepending sear engaging member 80 are rigidly attached. Member extendsvertically downward and has a transverse crosssection in the shape of aninverted T, the lower surface of the horizontal arm of said T beingprovided with a tooth or shoulder 8l. A lug 82 is also fixed to barrel11 adjacent the rear end of Ythe latter, said lug having an inclinedsurface 82a formed at the forward and upper end thereof. A bore 83 inbolt 56 receives firing pin 11, 18, the

Lug 63a normally extend-s into a groove 631)y latter.. extendingcentrally through cylindrical portion 51 of said bolt. Tip 19 (Fig. 11)is adapted in the extreme forward position of said pin to project beyondthe end of said portion a suflicient distance to strike and ignite acartridge held by said portion. A groove 85 is formed in the side wallof bore 83 to receive lug 82 and a slot 88 extends downwardly from saidbore through the bottom wall of said block, scar-engaging member 88being slidably mounted in said slot.

To operatively position ring pin 11, 18, a rod 81 (Figs. 7 and 10)extends into barrel 11 and has a head portion 88 which is xed in bore 83by a bayonet joint comprising a lug 89 on said head portion and a recess98 in the wall of said bore. A coil spring 9| is held under compressionbetween head 83 of said rod and pin 11, 18, being positioned around rod81 and within barrel 11. Spring 9| normally urges pin 11, 18 in thedirection of its firing position.

Novel means are provided for insuring that bolt 56 is locked against'movement before firing can take place and that during movement of thebolt the firing pin does not project beyond the end of bolt portion 51.The means comprise a depending lug 92 formed on member 64 and a recess93 in bolt 56 for said lug, said recess connecting with groove 85. Whenmember 64 is in de- Pressed position (Fig. 9), lug 92 engages inclinedsurface 82a of lug 82 and retracts firing pin 11, 18

relative to the bolt so that tip 19 is drawn within recess 83. Whenmember 64 is in elevated position so that bolt 56 is locked, lug 92 iswithdrawn from groove 85 and permits free movement of lug 82.

A novel unitary trigger mechanism is connected to receiver 26 andcomprises a housing 94 (Figs. 6, 8, and 12) having a trigger guard 95formed therewith and grip 30 fixed thereto by a screw 86. To `cock thefiring pin and control the release thereof, a scar `|83 (Figs. 8 and 12)and a lever |84 (Figs. 8 and 15) are provided and are pivotally mountedon housing 94 by a pin |85 carried by bearing members |86 formed withsaid housing. A shoulder |81 on sear |83 and a shoulder |88 on lever |84extend vertically in substantially the same lateral plane when saidlever and sear are in elevated position (Figs. 12 and and are adapted toengage shoulder 8| on member 88 as the bolt is returned from retractedposition. As a result, firing pin 11, 18 is held while.

bolt 56 moves relative thereto into locked ring position and said firingpin is thus cocked against the resistance of spring 9| (Fig. l0). Sear|83 is normally held in elevated operative position by a spring |89located in a recess ||8 (Fig. l2)

formed in housing 94 while lever |84 is similarly` held by a spring in arecess ||2 (Fig. 15) in said housing.

Lever |84 is automatically depressed and disengaged from member 88 bynovel means which comprise a cam or lug |3 on control link 68 (Figs. 6and 1). Counterclockwise rotation of link 68 which occurs at the end ofthe travel of bolt 56 from retracted position causes lug ||3 to e engagelever |84 and to depress the latter when control link 68 has raisedmember 64 into engagement with the ends of shoulders'65. Thus, the

firing pin cannot be released from cocked position until the bolt islocked in firing position.

Sear |83, if depressed after bolt 56 is locked, releases pin 11, 18,causing the latter to strike and ignite the cartridge, and novel means(Figs. 12 to 14), including a trigger I| 4, are provided for controllingthe displacement of said sear. As

' shown, said means comprise a link' ||5 connecting said sear to saidtrigger and a cam ||6 for said link, said cam being integral with acylindrical member ||6a rotatable through 180. A pin ||1 formed on saidlink is pivotally mounted in an opening H8 in said Sear, and a spring||9 guided in-a recess in said link bears against said sear and tends tohold said link in xed position relative to said sear. A finger 2|carried by trigger 4 engages a shoulder |22 on said link. The latter isprovided with an inclined surface ||5a for engaging one end of cam ||6when said cam is in the position shown in Figs. 12 and 13. Pressure onthe nger grip ||4a of the trigger which is pivotably mounted in a mannermore fully disclosed hereafter causes finger 2| nto apply a downwardforce to shoulder |22, and imparts (as viewed in Fig. 13) a pivotalcounterclockwise movement as well as a translatory downward movement tolink ||5. The translatory movement depresses sear |83 While'the pivotalmovement tends to free link I5 from finger |2| in such a manner thatwhen sear |83 has released the firing pin, link ||5 is disengaged fromthe trigger by the further movement of the trigger. This automaticallyreturns scar |83 to operative position while trigger ||4 remainspressed. The release of the trigger causes finger |2| to againoperatively engage shoulder |22.

When cam ||6 is rotated throu-gh 180 and assumes the position shown inFig. 14, the end thereof engaged by side I |5b of link ||5 presents aflat bearing surface to the right of said link. This prevents movementof said link to the right and causes nger |2| to remain in continuousengagement with shoulder |22, Accordingly, in this position of the cam,when trigger ||4 is pressed to depress sear |83, the latter remainsdisengaged from the firing pin until the trigger is again released. Aset screw |23 (Fig. 16) is provided for fixing member ||6 in a desiredposition, and a lever |24, operable by a small special tool, is locatedon the exterior of housing 94 and is connected to member |6a to providea means for changing the angular position of cam I6.

Trigger ||4 is pivotally mounted in a pair of recesses |25 in the sidewalls of housing 94 by a pair of pins |26 (Fig. 15) integrally formedwith said trigger. A iiat spring member |21 (Figs, 8, l2, and 15) isprovided to operatively position trigger i4, said member having the baseportion thereof dovetailed in a recess |28 in the upper wall of housing94 and being provided with a pair of arms |29 and |38 extending on bothsides of sear |83. Arm |29 is curved downward to engage the rear end oftrigger l I4 and acts as a cantilever spring to resiliently urge saidtrigger into inoperative position. Arm |38 has the end thereof held in agroove |32 in the side of housing 94 (Fig. 8).

A novel safety mechanism is provided and comprises a downwardly curvedelement |33 (Fig. l2) xed to sear |83 and a laterally extending shaft|34, said shaft having a slot or groove |35 formed therein in the samelateral plane as said element. The angular position of shaftA|34 iscontrolled by a lever |36 (Fig. 16) on the exterior of trigger housing94 and when shaft |34 is turned so that groove |35 opens in thedirection cf element |33, sear |83 is free for depression by the triggerto release the firing pin. However, when shaft |34 is turned so that theungrooved periphery thereof faces element |33, the latter is engaged bysaid shaft and the sear is positively locked against movement.

To hold bolt 56 in retracted position after the last cartridge `frommagazine 28 has been fired, a novel control member |31 (Figs. 6, 8, and16) is provided and is mounted for limited pivotal movement on pin |95,said member, as shown, comprising a finger |31a,v and a rearbolt-en-gaging portion or arm |315'. A spring |38 normally holds arm|3117 in raised position and said arm is adapted to slidably engage agroove |39 (Fig. '1) in bolt 56. Finger |31a extends forward through arecess |49 in the wall of receiver 29 (Fig. 6) and a slot (not shown) inmagazine 28. When follower 62 has introduced the last cartridge intochamber 59, finger |3111, is engaged thereby and tends to pivot arm |315downward. Accordingly, when bolt 55 is retracted, said arm becomes freeof groove |39 and moves downward to press against a lug |42 (Fig. 8)formed in the upper face of housing 94. As a result, the return movementof bolt 56 is prevented by the engagement of said Varm with the forwardend of the lower side wall of groove |39.

In order to iix member |6a in either of its extreme positions againstinadvertent and accidental movement a pin |43 extends into a peripheralgroove |44 in said member (Fig. 15), said groove subtending an angulardistance equal approximately to the amplitude of movement desired forsaid member. Groove |44 is provided with a pair of radial recesses |45for receiving said pin and determining the two positions of said member.A similar means for controlling shaft |34 of the safety mechanism in itsmovement into operative and inoperative positions is provided and, asshown comprises a peripheral groove |46s radial recesses |41 and a pin|48, said pin being guided by said groove .from one recess to the other.Pins |43, |48 are resiliently held in operative position by means of aflat spring member |31 which is in turn held in housing 94 by arm |39 ofspring |21.

To detachably secure housing 94 to receiver 29.

a lug 91 (Fig. 6) on said housing is insertable into a recess 98 in saidreceiver and a novel locking mechanism is provided at the rear end ofthe receiver. The locking mechanism comprises a pair of laterally spacedgrooves 99 (Figs. 3 and 5) and a cylindrical member |99 pivotablymounted in said receiver, member |99 having a pair of grooves 99a.adapted to be in alignment with grooves 99 when said member is ininoperative position, as shown in Fig. 3, A pair of laterally spacedupwardly extending lugs |9| are formed on housing 94, and each of saidlugs is adapted to t into one of grooves 99,9911. Lugs ||J| are providedwith substantially.semicircular recesses |92 which are coaxial withmember |99, when housing 94is operatively positioned in the receiver.Accordingly when member |99 is rotated through approximately 180 theungrooved periphery thereof engages the Walls of recesses |92 andtightly locks housing 94 in operative position (Fig. 5). Rotary motionmay be imparted to said member by means of an arm lila. attached theretoso as to be accessible from the exterior of the receiver (Fig. 8).

Novel means are provided for mounting the cartridge ejecting lug 63a andcomprise a flat metallic strip |49 (Figs. 20 and 21) to which acylindrical pin or shaft |59 is fixed, said pin hav, ing lug 63a formedtherewith. Shaft 5B extends into receiver 26 through an opening |5| inthe wall of said receiver and one end of strip |49 -lits into a slot |52while the other end is provided with a projection |53 which engagesa.recess |54 in said receiver. vBy raising the end of said strip fromrecess |54 and then pivoting the strip so that the other end is removedfrom slot |52, the strip, together with shaft |59 and lug 63a can beremoved from the receiver.

vA novel adjustable rear sight mechanism |55 is provided for cooperationwith a stationary forward sight |55 (Fig. 1) and as shown, (Figs. 17,18, and 19) said mechanism comprises a bracket |51 which may be securedto or formed integrally with receiver 2t. A sight member |58 having asighting recess |59 is adjustably mounted in said bracket. A pair offlanges |60 formed in the walls of said bracket extend inwardly andengage grooves 19| provided in the side edges oi member |59. Tovertically adjust member |58, a shaft 152 is provided and extendsthrough the side wall of bracket |51, said shaft having a peripheralgroove |53 formed therein for engagement with a lug |54 formed on member|53. The bottom wall of groove 153 serves to x' the vertical position ofmember |58, said wall having flat portions |630., i551) and |530 whichare spaced at different distances from the center of shaft 63 forengagement with lug |54. Rotation of shaft |52 determines which of saidportions engages said lug and accordingly controls the adjustment ofsaid member. To maintain lug |64 in groove |53 and in engagement withthe bottom wall of said groove, a plate spring |55 is operatively heldin a recess |96 in bracket |51 by a pin |61. Spring is adapted to bearagainst lug |64 and also against a second lug |58 formed on member |58,said second lug being similar to lug |54 and laterally spaced therefrom.A depending skirt |69 on member |58 cooperates with an upwardlyextending iiange |19 on bracket |51 to prevent light from passingbetween said bracket and said member when the latter is in raisedposition. To disassemble the sight mechanism pin |61 is removed andthis` frees member |58, shaft |62 and spring |55 for removal. Y

In operation, the rifle is adapted for either semi-automatic firing, i.e., one shot being iired for each pull of the trigger, or for fullyautomatic iiring, i. e., repeated ring, cam ||6 constituting theselector for the type of firing. The cycles of operations in thereceiver beginning with the ignition of a cartridge are substantiallysimilar for both kinds of firing.

The gases of the ignited cartridge enter cylinder 32 and actuate piston33 which, in turn, moves arm 49 rearward (Figs. 1 and 2). Lug 44 on saidarm pivots control link 69 (Fig. 6) depressing locking member 54 on'bolt 55 and disengaging said member from abutments 65 to free the boltfor rearward movement. Firing pin 11 and 18 is retracted within bolt 56by the depression of member 54, lug 92 engaging and holding said pin innon-iiring position. Further rearward movement of arm 40 is transmittedto bolt 56 by lug 45 which moves the bolt to the rear of receiver 25.

During retraction of the bolt, the spent cartridge shell is withdrawnfrom the barrel into cartridge chamber 59 and is ejected from saidchamber through opening |53. The open cartridge chamber is filled with afresh cartridge by magazine 28.

fter retraction bolt 56 is moved forward by spring 39, rod 49transmitting the motion to said bolt by means of lug 44. Portion 51 ofsaid bolt engages the rim of the cartridge and forces the latter intoiiring position in the barrel and firing pin 11, 18 is cocked by lever|54 and sear |93, the latter members engaging member 89 of said firingpin. When bolt 56 reaches the end of its forward travel, there is afurther forward movement of rod il which pivots link Si! and elevateslocking member 64, causing the latter to engage shoulders E5. As bolt 56becomes locked, lever H34 is depressed by cam |53 and is disengaged fromiiring pin il', i3. Lug 92 is also rendered inoperative. Thereafter,depression of sear |93 by trigger M releases firing pin 71, 18 andignites the cartridge to repeat the above cycle.

It is to be noted that if sear |83 remains depressed as the bolt returnsfrom retracted position, it does not engage the ring pin and the latteris held cocked only lby lever I. As a resultyring automaticallytakes'place Vwhen bolt Eit becomes locked in ring position, lever |04being then actuated, as above described, to release the firing pin.

For single shot firing, cam H5 is fixed so that sear |83 returns toelevated position immediately after release of the firing pin and whilethe trigger remains pressed. Thus, the trigger must be released to againbecome operatively connected to the sear and must be pulled afterrelease for each shot that is lired.

For automatic or continuous ring, cam H6 Y is xed so that sear |03 iscontinuously connected to trigger H4 and remains depressed as long astrigger H4 is pulled. The firing continues until the trigger is releasedor until the last cartridge in lthe magazine is fired.

The first loading of the cartridge chamber can be accomplished manuallyby retracting slide 45 when the latter is connected by pin 4S to arm 40.After the last cartridge is fired, follower 62 actuates member |31 andholds block 56 in retracted position until the magazine is removed.

There is thus provided a novel rifle adapted for automatic orsemiautomatic firing comprising a reciprocating bolt mechanism, a firingmechanism movable relative to said bolt mechanism and adapted to becocked in said bolt mechanism and actuating means responsive to theignition of a cartridge for energizing said mechanisms. The firingmechanism is released for igniting a cartridge only when the boltmechanism is locked 1n firing position and novel safety devices areprovided for insuring that this result be attained. A trigger mechanismis detachably secured as a. unit to the receiver and is provided withnovel means for controlling the firing mechanism, a member of saidtrigger mechanism cooperating with the cartridge magazine to control thebolt mechanism after the last cartridge is fired from the magazine.

Although only a single embodiment of the invention has been illustratedand described, it is to be expressly understood that the same is notlimited thereto. Various changes may be made in the design andarrangement of parts Without `departing from the spirit and scope of theinvention, as will now be apparent to those skilled in the art.
